Manual shutter resister array dongle for Polaroid pack cameras
This is a housing for a resistor array using a rotary switch that fits onto a Polaroid pack camera and controls the shutter.
Use 100 series files for models 100-400 and 400 series files for 400 series cameras.
Instructions on building the resistor array and modifying the Polaroid camera to use it can be found at http://polaroids.theskeltons.org/manuale.htm
